“Endocannabinoid system plays an important role in pathophysiologic processes such as immune functions and impacts on disease severity. Our previous study showed that cannabinoid receptor 2 (CB2) affects clinical course of respiratory syncytial virus (RSV) infection. In this study, we investigated the role of cannabinoid receptor 1 (CB1) in RSV immunopathology and its therapeutic potential in mice model. This study and our previous finding indicated that endocannabinoid signaling regulates the inflammatory response to RSV infection, and is a potential therapeutic candidate for alleviation of RSV-associated immunopathology.” https://www.ncbi.nlm.nih.gov/pubmed/29461930 http://online.liebertpub.com/doi/10.1089/vim.2017.0098
